1985 115 V4 no spark

[gerhardlombard]

Good day.

I own a 1985 Yamaha 115 V4.

My problem is that I get no spark at the plugs at all. I tested the kill switch and it is working. The Cdi seems ok but I do not get power on the top two wires on the CDI comeing from the magnito. Coils at plugs, everything tests positive.

Can you help me please.

You have to use a peak reading voltmeter to test charge coil, pulsor coils and CDI output voltage to get correct readings.
